Apple hopes to release a foldable 18.8-inch creaseless iPad by about 2028, Bloombergs Mark Gurman writes in todays Power On newsletter. The companys industrial design group has reportedly managed to create prototypes of this device that have a nearly invisible crease and would essentially be like two iPad Pros side-by-side.Rumors of a folding iPad have been floating in the ether for years, now. Recent ones include a smaller model that Apple would release in 2026 or 2027. Gurmans write-up today has strong echoes of the gargantuan 20-inch folding iPad / MacBook hybrid he detailed in 2022. That doesnt seem to mean that it will run macOS, but Gurman claims that it will have elements of both Macs and iPads and that iPadOS should be advanced enough to run macOS apps by 2028.Considering that Macs run iPhone and iPad apps now, its not outrageous to think the street could go both ways in time. It might help the value proposition, too; the 13-inch iPad Pro starts at $1,299, and whatever financial damage an iPad twice that size could incur would be a little easier to take coupled with the salve of being able to run macOS apps on it.Gurman says a foldable iPhone is still in the works, though he doesnt expect that before 2026 at the earliest, as other rumors have said. He also says information from his sources lines up with an alleged Apple internal display roadmap that made the rounds recently, tipping the 18.8-inch foldable iPad and Apples plans to release OLED MacBook Pros in 2026, followed by a MacBook Air OLED update in 2027.
